Pumice (filtered 3/8" to 1/4" in size) is relatively lightweight volcanic rock used as an amendment in all types of soil. Its porous composition allows it to retain moisture and nutrients during watering, and release them slowly over time as the root system requires. Think of these components as little batteries for your plants!

At Sol Soils, we are passionate about the beauty of plants and the natural world. But passion doesn't change the world without action. Through our partnership with Switch2Zero, we plant a tree for every bag sold to support Eden Reforestation projects across the globe. With each purchase of a Sol Soils product, you are directly contributing to the restoration of our planet's most beautiful and important ecosystems.
